What are the growth regions of roots?
The Meristematic Region or Growing PointThis region occurs immediately behind the root cap. The Meristematic region consists of meristematic tissue and is protected by the root cap. The cells are very activeand divide rapidly to form new cells which differentiate later to form more specialized root tissues. The cells of this region also replace the cells rubbed-off from the root cap and provide additional cells for the next region.FunctionThis is the region where the cells divide and where additional cells are provided for the zone of elongation.The Region of ElongationThe cells formed in the meristematic region undergo rapid growth in length. This causes the root to elongate and penetrate deeper into the soil in search for water and mineral salts. The meristematic and elongation zones are also referred to as the region of growth.FunctionIn this region the cells undergo rapid enlargement,i.e. the cells undergo rapid growth in length.The Root-hair RegionThe root hair region occurs a short distance above the region of elongation. Here a large number of fine, hair-like outgrowths are formed. The root hairs arise from the epidermal tissue of the root and are called root hairs. The root hairs are short and short-lived and develop on theprimary and secondary roots. A root-hair consists of the following parts: a thin cell wall, a thin lining of cytoplasm which contains thenucleus and a comparatively large vacuole containing cell sap.FunctionThe main function of the root hairs is to increase the area of absorption of the root.The Mature RegionThe mature region is situated above the root hair region. Here the root becomes thicker and secondary or lateral rootsare developed. The secondary roots in turn rebranch to form tertiary roots. Each lateral branch has its own cap, root hairs, meristematic, elongation and mature regions. The roots in this region are covered by a protective cork layer .FunctionsIn this region the cells undergo differentiation into specialized cells,(e.g. xylem and phloem).It also serves to anchor the plant.febbie
What are user-defined regions?
User-defined regions are regions defined by a special product or service.
Can regions overlap?
No, regions are separate and cannot overlap.
Why do you divide the earth into regions?
why do we divide the earh into regions?
How many regions in the Philippines as of 2011?
There are 17 regions as it is. :)
Where on a plant would you find meristematic tissue?
The meristematic tissue on a plant is found at the regions of active growing points such as shoot and root apices and intercalary regions having cambial activity.
What are the tissue cells of a plant organ?
Plant tissue systems fall into one of two general types: meristematic tissue and permanent (or non-meristematic) tissue. Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth.
What occurs as meristematic cells mature?
the cells of meristematic area are smaller.
Are undifferentiated cells found in meristematic tissue?
Only undifferentiated cells are found in meristematic tissue
What is the difference between meristematic and permanent tissue?
Meristematic tissues have the capacity to divide while permanent tissue lost the capacity of division. Meristematic tissue have thin cellulose walls while permanent tissue has a thick cellulose wall.
Why growth occures in certain regions rather than throughout the plant?
Because meristem is located either at the apical region or intercallary region and growth needs cellular division which occurs only in the meristematic cells.
Growthing points possess?
Meristematic cells
In which part of a pine tree stem is meristematic tissue located?
They are meristematic cambium cells located in a layer just inside the bark of trees and shrubs.
What happens to meristematic tissue when its loses ability to divide?
Meristematic tissues never lose the ability to divide untill and unless there is any human factor involved.
What is a type of cell that does divide actively?
A meristematic cell
Meristematic lateral location in plant cell?
plants
What is the main tissue in hydrilla plant?
meristematic tissue
